To (ZZZ whom donut concern: i

lie it known that I, MAURICE F. CARRIGAN, a citizen of the United States, residing at the city of Milwaukee, county of Milwaukee, and State of Wisconsin, have in vented new and useful Improvements in Cream- Separators, of which the following is a specificationf My invention relates to improvements in cream separators and it pertains more especially to the peculiar construction and relative arrangement of the liner plates and the vertical standards by which such liner plates are connected together, whereby said parts may, if desired/be separated from each other and reinoved'i'roni the receptacle, and, whereby, when in operation, the action of the apparatus may be accelerated. It is also a known fact that a vessel with a smooth. interior surlacemay be revol vedrapidly without communicating the same speed to its liquid contents. i

The object oliniy invention is among other things, first, to so construct thcdoperative mechanism of my device that the maximum speed of the receptacle will be communicated to its contents; second, to so construct the standards and liner plates that when connected together theywill-mutually support each other in position for use, and that WhOHHOl, in use they may,

if desired, be readily separated from each other and removed from the receptacle.

The construction of my. invention is explained by reference to the accompanying drawings in which,

Figure l is a vertical section of the revoluble receptacle in which is shown a side view of the liner plates and the vertical standards by which such liner plates are connected together. Fig. 2 is a top view of the upper conical liner plate of the series in connection with the vertical standards by which the liner plates of the series are connected together. Fig. 3 is a bottom view of the lower liner plate of the series shown in Fig. l, and Fig. '4 is a vertical section of the series of liner plates and vertical standards showing one mannor of connecting such parts together.

Like parts are identified by the sanle reference characters throughout the several views.

1 represents a revoluble receptacle of ordinary con-' ,cal sta'ndards 3, by which such liner plates are connected together. The vcrtical'standards 3 are prefer ably secured at their lowerends to the lower conical liner plate 4 of the series, whereby they are retained in their proper relative position to each other in the'inclosing receptacle. When thestandards 3 have been Specification of Letters Patent.

at their peripheries for the reception of the respective standards with which they register whereby when said liner plates are in place they will be caused to rev olve with and maintain the same relative position to each other. The lower side of the several. liner plates are preferably provided with downwardly projecting flanges or shoulders 7 located at short intervals apart by which said liner plates are supported from each other one above another at the proper relative distances apart. While I have shown the flanges 7 formed of separate pieces and secured to said liner plates said flanges may, if desired, be formed integrally with the liner plates 6 so as to perform the same functions, it being obvious that any other means for supporting said liner plates one above another at a required distance apart may be substituted for the flanges shown.

To provide ior binding the upper ends of the several standards 3 in their-proper relative position aroun d the longitudinal center oi the receptacle, I preferably provide'the upper conical liner plate 8 with apertures 9 formed back from the lower edge of said liner plates iorthe reception of the upperends of said standards which are inserted through said apertures, whereby it is obvious that the lower wall of said apertures will serve as a retaining hearing [or the upper ends of said standards and prevent the liability of such standards bOliigilllOWll outwardly by the centrifugal action of the device or from any other cause.

*It will of course be understood that the upper end of said standardsarc neeessarily cutaway so that the protruding eiid 10 of said standards will be of less width/ than the lower portion thereof and will be free to pass through the aperture 9 formed in the upper liner plate. l

while I have, for' convenience of illustration, shown the several liner plates of the series located at considerable distances apart, experience has demon strated that the action of the separator may be accelerated by greatly increasing the number of liner plates ina given space and for the best work the liner plates are preferably located within abouuone-sixteonth of an inch oi each other.

It will be understood that by the construction shown, the vertical standards 3 located as they are near the exterior walls of the receptacle will, as the receptacle is rapidly revolved, cause the contents to be revolved therewith, while it is obvious that were such'standards dispensed with the receptacle might be rapidly revolved without causing its'contonts to revolve with it at the same speed; that owing to the fact that the standards 3 are located in close proximity tially the same speed as the receptacle itself, wherebythe-several liner plates may to the walls oi the receptacle, the contentsoi the receptacle is necessarily caused to revolve at substana rapid rotation is communicated to the milk and the separation of the cream from the milk is greatly asceie rated. It will also be obvious that when desirous to remove the liner plates for the purpose of cleansing or repairing. the same this object can bereadily acwhich is thrown by the centrifugalaction of the deviceagainst the exteriorwails of the'receptacle will enter-the lower ends of the several ducts 12 when it willbe free to pass from the receptacle therefrom [through the outlet 13 of said ducts while the-cream or lighter products being acted upon will pass out through the upper duct 14 when the separation is complete.

.-The duct 14 through which the cream escapes is provided with a screw threaded stopper 15, which issupported in screw threaded bearings in the walls of the duct and serves to regulate the'discharge of cream.

from the separator. When the duct is opened a large percentage of milk will escape with the cream. When,

however, it is partialiy'closed, a higher percentage of cream will escape. r i I The vertical standards Spreierabiy extend upward so as to contact with the cover 11,,whercby when the cover is in place it will bear upon the upper ends of said standards and facilitate holding said standards and'liner plates thereon rigidly in place within the receptacle. with a plurality of downwardly. projecting lugs 16 which are adapted as the cover is secured in place to bear upon the upper edge of the upper liner plate and serveto bind said liner pl his in their proper relative position to each other and their supporting standards.

17 is an inlet tube which communicates irom the top of the cover 11 through the central apertures 18 of the several liner plates and is connected at its lower The cover 11 is also preferably provided whereby when said upper liner plate is ends of said standards will be secured together by said end to the upper end of the spindle 19 by screw thread- 7 ed bearings. The upper end ofsaid duct 17 is provided with a radial'fiange 20 which bears upon the upper end of said cover, whereby as said duct 17 is turned down upon the upper end of said spindle it serves to bind all oi said cooperative parts together including the vertical standards the liner plates supported thereon,

The lower end of .the duct 17 is provided wit-hapiurality oi apertures 21 through which the milk escapes from said duct into the inclosing receptacle below'the lowest liner plate of said series.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,

1. In a cream separator the combination of a revoluhie receptacle, a plurality 'of vertical standards arranged in ,a circular series around a common center within and in close proximity to the vertical inciosing wall oi! said receptacle, a series of conical shaped liner plates-provided with a plurality of flanges one above another from [each other, the lower iinerplate of said series being rigidly connected with the lower end otsaidstandards and each succeeding liner plate above the lower being detachably supported by said flanges from each other around said standards.

. 2. In a cream separator of the hlnation of a revolubie receptacle, of a plurality of vertica'l standards arranged in a circular series around a com inon center in close proximity to the vertical walls of said receptacle, a plurality of flanges interposed between and adapted to support said liner plates one above another at slight distances apart around said standards,.the lower being rigidly affixed to and supend of said standards ported from the lower liner plate while the upper ends oi. said standards have contact bearings against the cover of said receptacle, each successive liner plate between the lower and upper one being provided with a plurality of recesses for the reception of said standards, the upper class described the com.-

the spindle and inclosingreceptacle.

by which they are supported linerpiate of said series being provided with apertures upper ends of said standards in place the upper for the reception of the liner plates. v
